Standard staging investigations (e.g. computed tomography and positron emission tomography\u2013computed tomography).<\/jats:p>\n <\/jats:sec>\n \n Reference standard<\/jats:title>\n Consensus panel decision using 12-month follow-up data.<\/jats:p>\n <\/jats:sec>\n \n Main outcome measures<\/jats:title>\n The primary outcome was per-patient sensitivity difference between whole-body magnetic resonance imaging and standard staging pathways for metastasis. Secondary outcomes included differences in specificity, the nature of the first major treatment decision, time and number of tests to complete staging, patient experience and cost-effectiveness.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n Streamline C \u2013 299 participants were included. Per-patient sensitivity for metastatic disease was 67% (95% confidence interval 56% to 78%) and 63% (95% confidence interval 51% to 74%) for whole-body magnetic resonance imaging and standard pathways, respectively, a difference in sensitivity of 4% (95% confidence interval \u20135% to 13%; p<\/jats:italic>\u2009=\u20090.51). Specificity was 95% (95% confidence interval 92% to 97%) and 93% (95% confidence interval 90% to 96%) respectively, a difference of 2% (95% confidence interval \u20132% to 6%). Pathway treatment decisions agreed with the multidisciplinary team treatment decision in 96% and 95% of cases, respectively, a difference of 1% (95% confidence interval \u20132% to 4%). Time for staging was 8 days (95% confidence interval 6 to 9 days) and 13 days (95% confidence interval 11 to 15 days) for whole-body magnetic resonance imaging and standard pathways, respectively, a difference of 5 days (95% confidence interval 3 to 7 days). The whole-body magnetic resonance imaging pathway was cheaper than the standard staging pathway: \u00a3216 (95% confidence interval \u00a3211 to \u00a3221) versus \u00a3285 (95% confidence interval \u00a3260 to \u00a3310). Streamline L \u2013 187 participants were included. Per-patient sensitivity for metastatic disease was 50% (95% confidence interval 37% to 63%) and 54% (95% confidence interval 41% to 67%) for whole-body magnetic resonance imaging and standard pathways, respectively, a difference in sensitivity of 4% (95% confidence interval \u20137% to 15%; p<\/jats:italic>\u2009=\u20090.73). Specificity was 93% (95% confidence interval 88% to 96%) and 95% (95% confidence interval 91% to 98%), respectively, a difference of 2% (95% confidence interval \u20132% to 7%). Pathway treatment decisions agreed with the multidisciplinary team treatment decision in 98% and 99% of cases, respectively, a difference of 1% (95% confidence interval \u20132% to 4%). Time for staging was 13 days (95% confidence interval 12 to 14 days) and 19 days (95% confidence interval 17 to 21 days) for whole-body magnetic resonance imaging and standard pathways, respectively, a difference of 6 days (95% confidence interval 4 to 8 days). The whole-body magnetic resonance imaging pathway was cheaper than the standard staging pathway: \u00a3317 (95% confidence interval \u00a3273 to \u00a3361) versus \u00a3620 (95% confidence interval \u00a3574 to \u00a3666). Participants generally found whole-body magnetic resonance imaging more burdensome than standard imaging but most participants preferred the whole-body magnetic resonance imaging staging pathway if it reduced time to staging and\/or number of tests.<\/jats:p>\n <\/jats:sec>\n \n Limitations<\/jats:title>\n Whole-body magnetic resonance imaging was interpreted by practitioners blinded to other clinical data, which may not fully reflect how it is used in clinical practice.<\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n In colorectal and non-small-cell lung cancer, the whole-body magnetic resonance imaging staging pathway has similar accuracy to standard staging pathways, is generally preferred by patients, improves staging efficiency and has lower staging costs.
